Lighttpd 500 Error

simultaneous connections open to the server Added by Devilicious almost 5 years ago My server info can be found from the end of the post. Problem:I'm doing a stress test to my server with

Lighttpd Debug Log

some windows stress test tool. It's set to simulate ~2 000 page lighttpd error log requests per minute. Those requests go to my PHP api which uses mysql and facebook API to deliver the asked info to the user. API response time is from around 2 seconds to 40 seconds (due to the slowness of Facebook graph api mainly) so when doing 2000 page requests per minute, some of them will load about 40 seconds and therefor there are many open connections. The problem itself is, when about 400 (the number isn't exactly 400, but should be around it) users are sitting with open connection and waiting for the response from the API new users get Internal Server Error 500. When doing the same stresstest against a static php file (phpinfo() in it), no errors. But again, as the stresstester program doesn't open all the 1000 connections at the same time, there weren't so many open connections this time (compared with the API stresstest) Question:How can i resolve this? What should i change to make the server accept more concurrent requests so there could be more open connections.Also, the request go slower and slower as the open connection count rises (logical, i know), but i have the feeling that my server can do better than this (linode.com graphs show that during the stresstest server CPU useage is around 14%, i couldn't find mem useage graph tho) Side question:I can't find a log file that logs those errors. Is it just me or the system doesn't actually log them? I'm just thinking that maybe there's more info in the log file about why the users get error 500. I'm all new in this server managing stuff. Please describe every step as good as possi

Join Date Feb 2007 Beans 46 Re: cgi & lighttpd 500 internal server error I don't think it's you, I think it's lighttpd in 9.10 (assumes you use 9.10). I'm still having problems with CGI. This is true for systems upgraded to 9.10 from an earlier version, and fresh installs. One fix turned out to be the opposite of a fix for an earlier lighttpd bug or bugs (#292347 and #179484). The fix for those bugs is to comment out
